James Corden did an amazing job when he hosted the Grammys on Sunday night. In addition to his hilarious opening number [4], the star pulled out one of his best skits from The Late Late Show: Carpool Karaoke [5]. After joking about how the beloved skit is the only reason he's well known, he enlisted the help of some of the night's biggest stars to sing along to Neil Diamond's "Sweet Caroline." [6] The best moment of the whole thing, though, was when Beyoncé's 5-year-old daughter, Blue Ivy, jumped in. Trust us, you'll melt.
